A man driving a car sees a deer crossing the road and brakes the car with a force of 100 N. The car stops after traveling 5m. What is the work done on the car?

Answers

Answer:

Workdone = 500Nm

Explanation:

Given the following data;

Force = 100N

Distance = 5m

To find the workdone;

Workdone is given by the formula;

[tex] Workdone = force * distance[/tex]

Substituting into the equation, we have

[tex] Workdone = 100 * 5 [/tex]

Workdone = 500Nm

Determine the stopping location of the prize wheel. At this moment it is centered on the number 5. It is spinning with an energy of 6.19 J. It is slowing at a rate of 1.800 rad/s/s.

The disk is made from a wood with a density of 478.0 kg/m^3. The disk is 29.0 mm thick and has a radius of 33.0 cm.

Predict the angular displacement it will go through and predict the number on which the wheel will stop. To be safe, you will also get one number the right and to the left of the number you chose.

The wheel will spin clockwise. The wheel goes from 1 to 36.

Moving a spring toy up and down will create what kind of disturbance?

parallel to the wave motion

in a circular motion

in the same direction as the wave motion

perpedicular to the wave motion

Answers

Answer:

Perpindicular to the wave motion.

Explanation:

Moving a spring toy up and down will create a disturbance in the same direction as the wave motion.

We can classify waves by the direction of wave motion in which case waves are classified into;

Transverse wavesLongitudinal waves

Longitudinal waves are waves in which the direction of disturbance is in the same direction as the wave motion. The wave along a spring is a longitudinal wave therefore; moving a spring toy up and down will create a disturbance in the same direction as the wave motion.

Why did you need to heat the water to make the nectar?

A. Heating the water increases the solubility of the sugar.
B. Heating the water decreases the melting point of the sugar.
C. Heating the water increases the boiling point of the sugar.
D. Heating the water increases the particle motion of the sugar.

Answers

Answer:

D

Explanation:

Heating up the solvent gives the molecules more kinetic energy. The more rapid motion means that the solvent molecules collide with the solute with greater frequency and the collisions occur with more force. Both factors increase the rate at which the solute dissolves.

A spring is compressed between two blocks, one with a mass of 2 kg and the other with a mass of 3 kg. If the 2 kg block has an average acceleration of 6 m/s^2 when the spring acts on it, what will be the average acceleration of the 3 kg block???

Answers

Answer:

2=6

3=9

Explanation:

I think this is right I'm not sure but I have done problems like this and did based on what I remember.

The average acceleration of the 3 kg block is 4 m/s².

The given parameters;

mass of first block = 2 kgmass of second block = 3 kgacceleration of the first block, = 6 m/s/s

According to Newton's third law of motion, action and reaction are equal and opposite.

The force exerted on both blocks are equal and opposite.

[tex]F = ma\\\\m_1 a_1 = m_2a_2\\\\a_2 = \frac{m_1 a_1}{m_2}\\\\a _2 = \frac{2\times 6}{3} \\\\a_2 = 4 \ m/s^2[/tex]

Thus, the average acceleration of the 3 kg block is 4 m/s².

An object moving with a speed of 35 m/a and has a kinetic energy of 1500j, what is the mass of the object

Answers

Explanation:

Speed or velocity (V) = 35 m/s

Kinetic energy (K. E) = 1500 Joule

mass (m) = ?

We know

K.E = 1/2 * m * v²

1500 = 1/2 * m * 35²

1500 * 2 = 1225m

m = 3000 / 1225

m = 2.45 kg

The mass of the object is 2.45 kg

A construction worker pushes a wheelbarrow 15 m with a horizontal force of 17 N. How much work is done by the worker on the object?

Answers

Answer:

The work done by the worker on the object is 255 J

Explanation:

Work is defined as the force that is applied on a body to move it from one point to another.

When a net force is applied to the body or a system and this produces displacement, then that force is said to perform mechanical work. This work can be positive if the system gains energy or negative if the system loses energy.

In the International System of Units, work is measured in Joule. Joule is equivalent to Newton per meter.

The work is equal to the product of the force by the distance and by the cosine of the angle that exists between the direction of the force and the direction that travels the point or the object that moves.  

In this case, the angle between the force and the displacement is 0 degrees. Then the cosine of 0 degrees will have a value of one. So work is calculated as the multiplication between force and distance:

W= 17 N* 15 m

Solving:

W= 255 J

The work done by the worker on the object is 255 J

Answer:

Explanation:

F = ma

m = F/a

m = 107.2/1.6 = 67 kg

so Naoki's mass must be the total mass - mass of the bike

Discuss a time when you made an impulsive decision. What was the decision? Why did you make your decision
impulsively? What were the consequences of the decision? If you had the decision to make all over again, how would you
change your decision?

Answers

EXPLANATION: In Summer 2016, I took the decision to buy a car which was impulsive in nature. The car was being offered at a huge stock clearance discount by the dealer and the car was also a limited version much loved by my father. So, to get the last minute deal I bought the car within a week's notice.
ANSWER 2: The decision was taken because the car was limited and it was a huge stock clearance from the dealer's end after which the car's production was stopped and it won't be available. The car being my father's favorite, I wanted to gift it to my dad.
ANSWER 3: The consequence of the decision was I had to get loan from finance company with a tenure of 5 years. The car was well out of my budget. I made a down payment of whatever savings and I got my loan.
ANSWER 4: If the decision was to made all over again, I would prefer to calculate my finance first. I would prefer a used car to buy for me or my dad rather than running for last minute deals from the dealers. The used car will be well within my budget and would also be offering the same features as the new car would have been.
